SNOW-CSA Database Administration and CMDB Practice Question
This SNOW-CSA practice question tests your understanding of database administration and cmdb. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which two statements are true about CMDB relationships? (Select two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Relationship types are defined in the cmdb_rel_type table.
Option A is correct because the `cmdb_rel_type` table stores the definitions of all relationship types in the ServiceNow CMDB, such as 'Depends on' and 'Used by'. Each record in this table defines a unique relationship type with its name, direction, and cardinality constraints. This table is the authoritative source for the relationship types available in the system.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Relationship types are defined in the cmdb_rel_type table.
Why this is correct
The cmdb_rel_type table defines all relationship types.
Related concept
Read the scenario before looking for a memorised answer.
✓
Relationships are stored in the cmdb_rel_ci table.
Why this is correct
The cmdb_rel_ci table stores all CI relationships.
Related concept
Read the scenario before looking for a memorised answer.
✗
Relationships can only be created manually.
Why it's wrong here
Relationships can be created automatically by discovery.
✗
A CI can have only one relationship of a given type.
Why it's wrong here
A CI can have multiple relationships of the same type (e.g., multiple 'Depends on').
✗
The 'Depends on' relationship is default for all CIs.
Why it's wrong here
There is no default relationship type.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the `cmdb_rel_type` table (which defines relationship types) with the `cmdb_rel_ci` table (which stores actual relationships), and mistakenly think relationships are stored in the type table or that all CIs automatically have a 'Depends on' relationship.
Detailed technical explanation
How to think about this question
The `cmdb_rel_ci` table (Option B) stores the actual relationship instances, linking two CIs via a specific relationship type from `cmdb_rel_type`. Under the hood, ServiceNow uses a directed graph model where each relationship has a parent and child CI, and the `cmdb_rel_type` table defines the type's cardinality (e.g., one-to-many) and whether it is symmetric. In real-world scenarios, misconfigured relationship types can cause incorrect service mapping or impact analysis, especially when using the 'Depends on' type for critical application dependencies.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the SNOW-CSA exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
